U11D0 FIAT Meaning

This diagnostic checks for the availability of the Ignition Key Status signal which is sent by the Body Controller Module (BCM) via a Controller Area Network (CAN) message. The Ignition Key Status possible values include the following: 0) Lock, 1) Off, 2) Accessory, 3) Off and Accessory, 4) Run, 5) Start, and 7) Signal Not Available (SNA). The diagnostic checks the signal availability by checking if the received value is not equal to the SNA default value. When the signal is not available, the BCM sends an SNA default value to the Transmission Control Module (TCM). If the TCM reads this value then the Diagnostic Trouble Code (DTC) U11D0 is set.
